Description

Technical Field

[0001] The utility model relates to a medical device, in particular to a drainage device for cleaning anorectal feces. Background Art

[0002] ICU patients often lose the ability to take care of themselves due to their critical condition, impaired consciousness, etc. The incidence of diarrhea and fecal incontinence is high. Due to the continuous outflow of feces, the skin around the anus and perineum of the patient becomes moist and corroded by metabolic products. In addition, repeated scrubbing can easily lead to incontinence-related dermatitis such as skin redness, peeling, and erosion, which reduces the patient's comfort, aggravates the patient's condition, and increases the difficulty of nursing.

[0003] If the patient has frequent diarrhea or fecal incontinence, the traditional method is to place a nursing pad or paper towel under the buttocks and clean, scrub, and change the bed sheets in time. However, it is difficult for some critically ill patients to frequently turn over and clean their stools because they undergo bedside treatments such as CRRT and ECMO. Therefore, in some hospitals, ICU medical workers have made some devices to continuously drain stool, such as using abdominal drainage tubes, enema anal tubes, or even modified endotracheal tubes to be placed in the rectum of incontinent patients to continuously drain stool. However, these drainage tubes can only drain stool. If you want to flush the anorectum, you need to pull out the drainage tube and reinsert the cleaning tube. Frequent insertion and removal of these catheters will cause some potential risks or complications to the anorectum, such as rectal erosion, perforation, and even heavy bleeding. Utility Model Content

[0004] In order to overcome the above technical defects, the utility model proposes a fecal fluid drainage device with drainage and flushing functions to improve the anorectal care effect.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is: a fecal liquid drainage device, including a catheter and a drainage tube and a flushing tube connected to the catheter, the insertion section of the catheter has a plurality of through holes, the catheter is a double-cavity structure, the catheter is connected to the drainage tube and the flushing tube through a three-way valve, and the drainage tube and the flushing tube are both provided with a speed regulator.

[0006] Preferably, a baffle is provided at the insertion section of the catheter, and an anal patch is attached to the surface of the baffle.

[0007] Preferably, the drainage tube and the flushing tube are connected to a suction device with a piston structure.

[0008] Preferably, the cylinder of the aspirator is inserted with a push-pull rod and has a built-in piston connected to the push-pull rod, and the cylinder is provided with a drainage interface and a flushing interface connected to the drainage tube and the flushing tube respectively.

[0009] By implementing the technical scheme of the utility model, the catheter is connected to the drainage tube and the flushing tube through the three-way valve, realizing the dual medical functions of draining feces and flushing the anorectum, improving the medical effect, and under the adjustment of the speed regulator, the drainage pressure is adapted to the needs of the disease, reducing the discomfort caused by negative pressure drainage, and under the switch of the speed regulator, the medical operations of drainage and flushing can be switched freely, and the flushing function can be directly exerted without pulling out the catheter after the drainage is completed, reducing the number of intubations, helping patients with fecal incontinence to defecate, and having strong medical practicality.
